On foot, Laura ran 2:08:38 and Edward ran 48:29 — Edward was 1:20:09 faster than Laura. Laura took official place 1319th (time-based 1327th) and Edward took official place 2nd (time-based 1st). Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 24:19 from Muir Woods to Cardiac.
